Docker Image

Docker Pulls Docker Image Size (latest by date) Platforms

This is a Docker container that uses domain-scan to scan domains using pshtt, trustymail, and sslyze.

This Docker container is intended to be run via cisagov/orchestrator.

N.B.: The secrets in the src/secrets directory are only used when testing via the docker-compose.yml composition. Normally this Docker container is run via the Docker composition in cisagov/orchestrator, which expects the secrets in a different location.

Running

Running with Docker

To run the cisagov/scanner image via Docker:

docker run cisagov/scanner:1.3.7

Running with Docker Compose

  1. Create a docker-compose.yml file similar to the one below to use Docker Compose.

    ---
    version: "3.7"
    
    services:
      scanner:
        image: cisagov/scanner:1.3.7
        volumes:
          - type: bind
            source: <your_log_dir>
            target: /home/cisa/shared
  2. Start the container and detach:

    docker compose up --detach

Using secrets with your container

This container also supports passing sensitive values via Docker secrets. Passing sensitive values like your credentials can be more secure using secrets than using environment variables. See the secrets section below for a table of all supported secret files.

  1. To use secrets, create an aws_config file in this format:

    [default]
    aws_access_key_id=AKIAIOSFODNN7EXAMPLE
    aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
    region=us-east-1
    output=json
  2. Then add the secrets to your docker-compose.yml file:

    ---
    version: "3.7"
    
    secrets:
      aws_config:
        file: ./secrets/aws_config
    
    services:
      scanner:
        image: cisagov/scanner:1.3.7
        volumes:
          - type: bind
            source: <your_log_dir>
            target: /home/cisa/shared
        secrets:
          - source: aws_config
            target: aws_config

Updating your container

Docker Compose

  1. Pull the new image from Docker Hub:

    docker compose pull
  2. Recreate the running container by following the previous instructions:

    docker compose up --detach

Docker

  1. Stop the running container:

    docker stop <container_id>
  2. Pull the new image:

    docker pull cisagov/scanner:1.3.7
  3. Recreate and run the container by following the previous instructions.

Image tags

The images of this container are tagged with semantic versions of the underlying example project that they containerize. It is recommended that most users use a version tag (e.g. :1.3.7).

Image:tag Description
cisagov/scanner:1.3.7 An exact release version.
cisagov/scanner:1.3 The most recent release matching the major and minor version numbers.
cisagov/scanner:1 The most recent release matching the major version number.
cisagov/scanner:edge The most recent image built from a merge into the develop branch of this repository.
cisagov/scanner:nightly A nightly build of the develop branch of this repository.
cisagov/scanner:latest The most recent release image pushed to a container registry. Pulling an image using the :latest tag should be avoided.

See the tags tab on Docker Hub for a list of all the supported tags.

Volumes

Mount point Purpose

Building from source

Build the image locally using this git repository as the build context:

docker build \
  --build-arg VERSION=1.3.7 \
  --tag cisagov/scanner:1.3.7 \
  https://github.com/cisagov/scanner.git#develop

Cross-platform builds

To create images that are compatible with other platforms, you can use the buildx feature of Docker:

  1. Copy the project to your machine using the Code button above or the command line:

    git clone https://github.com/cisagov/scanner.git
    cd scanner
  2. Create the Dockerfile-x file with buildx platform support:

    ./buildx-dockerfile.sh
  3. Build the image using buildx:

    docker buildx build \
      --file Dockerfile-x \
      --platform linux/amd64 \
      --build-arg VERSION=1.3.7 \
      --output type=docker \
      --tag cisagov/scanner:1.3.7 .
